Product Description
Corden EPS biaxial geogrids are a range of premium quality punched and drawn polypropylene geogrids that optimise the rib height and open aperture area to maximise stone penetration and interlock with the grid. They are comparable to other market leading products and offer a design life in excess of 100 years. They can solve pavement problems by giving omni-axial reinforcement to granular sub-bases, piling platforms, capping layers and railway ballasts in areas of weak or variable soils.
When granular particles are compacted over these grids, they partially penetrate and project through optimised apertures to create a strong and positive interlock. The load dispersal effect from the interlocking increases shearing resistance within the soil and allows the sub-base thickness to be decreased (or the design life increased), ultimately reducing construction time and costs and improving the whole-life cost.

Corden EPS biaxial geogrids can be used in single or multilayers. The platform thus created provides tremendous load dispersal, allowing previously weak soils to be reclaimed for development such as foundations, motorways, railways and airport runways. Corden EPS Biaxial geogrids are available in two aperture sizes, to suit any fill material.
